8 ■ 1. Your Watch  World Time Eco-Drive Radio Controlled Watch

This watch is a radio controlled watch, which receives the standard time radio waves that are broadcast from radio wave in three regions, Japan, the USA and (Germany), and uses these waves to automatically correct the time and . (p. 18)

◎ Automatic reception: The watch will automatically receive the radio wave up to three a , at 2 a.m., 3 a.m. and 4 a.m., and adjust the time and date accordingly. However, note that if the watch successfully receives the radio wave at 2 a.m., it will not perform automatic reception again at the later times. The 4 a.m. automatic reception can be changed to any time of the day. ◎ On demand reception: The radio wave can be received at any time of the day to adjust the time and date. In the that a radio signal cannot be received, the watch can be manually set and will operate keeping time within +/- 15 per .

9 ◎ UTC (Coordinated ), the time and date of 43 cities (or regions) from around the world and one city (any can be set) can be displayed and easily called up. It is convenient when traveling overseas on business or vacation. Daylight saving time can also be set. (p. 44)

This is a multi-functional Eco-Drive watch, which is equipped with a solar power function for powering the watch by converting light energy into electric energy.

◎ Charge level display function: This function displays the charge level in four grades, to give an approximate indication of how much the rechargeable cell is charged. (p. 38)

◎ Power saving function: The watch is equipped with two power saving functions. If the watch face is not exposed to light for 30 or longer, all the LCD display sections turn off (Power saving 1). If the watch face is then not exposed to light for one or longer, the hands are stopped in order to minimize the watch’s power consumption (Power saving 2). (p. 92)

10 Important Points Regarding Radio Wave Reception There are two methods to receive radio signals during normal operation, Automatic and On Demand. The internal unidirectional may be weakened by or building structures, which may require the user to place the watch near a window. When receiving radio waves: * Remove the watch from your wrist * Face the 9:00 position of the watch towards a window * Place the watch on a stable surface * Do not move the watch during this process. of the watch may cause incomplete reception. During radio reception, the second hand of the watch moves in reception level. * When reception is complete, the watch will return to movement at one-second intervals. Reception can take from about 2 minutes to a maximum of 15 minutes.

If you are unable to receive radio waves, please inquire to the Citizen Service Center.

13 [Checking the Reference Position]

Before using the watch, confirm that the hands are aligned with “0”, similar to when setting weighing scales ◎ The reference position may become misaligned when the watch is exposed to strong magnetism, static electricity or impacts. Even if radio waves are received, the correct time will not be indicated unless the watch hands are aligned to the correct reference position. Check that the hands are properly aligned with “0”.

Examples of magnetic products that can affect the watch. • Health products (for example, medical and that have magnetic fields) • Refrigerators (magnetic part of the door) • Electromagnetic cookers • Bags (with magnet fasteners) • Mobile phones (speaker part) Keep the watch away from items similar to those above. 14 1.

Caution: If the home city is set to a city that is outside the reception area, the radio wave cannot be received. Turn off the automatic reception and set the time manually. (p. 66 〜 69)

17 ■ 4. Radio Signal Reception Three types of radio signal reception are possible: automatic reception, on demand reception and recovery automatic reception. There are three modes where reception is possible: time (TME), calendar (CAL) and receive set (RX-S). The watch cannot receive signals in any other mode. Display the home city in digital display 2 when receiving the radio wave.

• Reception is not possible unless the crown is in the normal position. • If the home city is “UTC”, reception is not possible. • Reception is not possible during chronograph or timer measurement. • The reception level may change depending on the surrounding environment. While referring to reception level (H, M or L), change the watch location, direction and angle to try to receive the radio wave. • When the watch is receiving the radio wave signal, all of the hands will stop. To check the time, hold the lower right button (A) for 2 seconds to cancel the radio wave reception. The hands will then return to the current time.

18 Automatic reception • It is not necessary to operate buttons during automatic reception. • The watch will automatically receive the radio wave every day at 2 a.m., 3 a.m. and 4 a.m. • The 4 a.m. reception can be changed to any time of the day. (p. 66 〜 69) • Reception can be set to OFF. (p. 66 〜 69)

1. Remove the watch from your wrist and place on a stable surface in a location, such as near a window, from which radio waves can be easily received, pointing the 9:00 side (reception antenna position) in the direction of the radio wave transmitter. 2. The watch will automatically receive the radio wave every day at 2 a.m. An antenna for receiving the radio If it successfully receives the wave, reception is signals is located inside the watch not performed at 3 a.m. and 4 a.m. (on the 9:00 position).

19 On Demand Reception (Manual Reception) • Signals can be received at any time. [Mode hand position when receiving] 1. Pull the crown out to position 1 and turn to align the mode hand with the CAL, TME or RX-S position. 2. Return the crown to the normal position. 3. Remove the watch from your wrist and place on a stable surface near a window where the radio signal can be easily received.

4. Point the 9:00 side of the watch in the direction of the radio wave transmitter, and hold down the lower right button (A) for more than 2 seconds. Release when the confirmation tone sounds and the second hand stops at RX. The second hand will then move to H, M or L. * Do not move the watch during reception. 5. When the radio wave has been properly received, the second hand will automatically move from H, M or L to the time that was received, all the hands will be corrected, and the second hand will return to 1-second interval movement. 20 Recovery Automatic Reception (Automatic Reception) • If the watch stops due to insufficient charging, expose the watch to sunlight to recharge it. When the watch is recharged sufficiently, it will automatically receive the radio wave once.

* Regularly charge your radio controlled watch so it does not become insufficiently charged. The radio wave reception can be checked with “Confirming Reception Status”. (p. 26)

21 If the watch has received insufficient light for charging or has been kept in a dark location for an extended period of time (one week or more), the Power Save Feature of the watch is activated and the hands of the watch stop. Even though the watch will not show movement, the correct time is kept in memory. When the watch is in the Power Save mode, it will continue to keep the correct time internally. In some instances, “Automatic Reception” may not be successful due to a weak signal reception. When resuming use of the watch after the power save mode has been activated for an extended period of time, you can cancel the Power Save function by placing the watch in light sufficient for charging and performing the “On Demand” reception process to correctly set the time and date. (Refer to page 92 for information on the Power Save Function.)

22 ■ 5. Poor Reception Areas It may not be possible to receive radio waves under environmental conditions where reception is difficult or in areas susceptible to radio noise, such as those shown in the illustrations below. While referring to the reception level display, try to find a location with better reception.

◆ Near high-tension electrical ◆ Inside vehicles, including ◆ Inside reinforced concrete lines, railway overhead wires cars, trains and aero planes buildings or underground or communication facilities

Solution: Rotate the scales so that the value on the inside scale corresponding to 22.5 on the outside scale is equal to the value on the outside scale corresponding to 10 on the inside scale, and read off the answer of 15 at that location.

87 ■ 24. Solar Power Function This watch uses a rechargeable cell to store electrical energy. When the watch is fully charged, it will run for about 6 .

For best operation, charge your watch in direct sunlight.

◆ An effective way of charging the watch is to keep it in a bright location when you are not wearing it, such as near a window where it can receive direct sunlight.

88 ◆ Wearing clothes with long sleeves makes it difficult for the watch to get the necessary light, resulting in insufficient charging. We recommended that you charge the watch for a long time in direct sunlight once a month.

[Caution] Do not charge on surfaces that can easily become hot, such as a car dashboard.

89 ■ 25. Characteristics of the Eco-Drive Watch

◎ When the watch is insufficiently charged, the indication will be changed as follows:

[Normal display] [Insufficient charge warning] The watch has been insufficiently charged because the watch face, which contains the , has not received sufficient light.

When the watch stopped due to insufficient charging • It takes at least 30 minutes to recharge sufficiently to perform recovery automatic reception, even if the watch is being exposed to light. After recovery, refer to “Guide to Charging Time” (p. 96) and sufficiently charge the watch. * 2. If the watch failed to perform recovery automatic reception • The time is incorrect even if the second hand moves at 1-second intervals, so after fully charging the watch, set the time manually or perform on demand reception.

91 A. Power Saving Function If the watch face is not exposed to light for a long time, the power saving function is activated to minimize the battery consumption. • Power saving 1: When power is not generated for more than 30 consecutive minutes, the digital displays go off to save power. • Power saving 2: When the power saving 1 condition continues for 7 days or longer, to save power, the hour hand, minute hand, second hand and 24-hour hand move to the reference position, and the charge level indicator and UTC hands (hour and minute) stop in their current positions. • The correct time continues to be kept inside the watch. • The alarm tone will not sound. [Normal diaplay] [Power saving 1] [Power saving 2] The digital display areas Digital display all go off and areas all go off the hands stop.

Not exposed to light Not exposed to light for 30 minutes or more for 7 days or more 92 The power saving function will be automatically canceled when the watch face is exposed to light.

• When power saving 1 is canceled, the digital display is restored. • After the power saving 2 has been canceled, the hands will rapidly move to the current time and return to 1-second interval movement. • If the watch is insufficiently charged, the second hand will begin the 2-second interval movement. Return the second hand to 1-second interval movement by sufficiently charging the watch.

93 B. Insufficient Charge Warning Function When the charge level indicator reaches level 0, the second hand’s movement changes from 1-second intervals to 2-second intervals and the mark flashes in digital display 1 to show that the watch is insufficiently charged. The watch will stop due to insufficient charging about 3 2-second interval movement days after starting the 2-second interval movement if kept in a place with no light. [Caution] During 2-second interval movement, the digital displays and watch operations change as follows. • The time cannot be adjusted manually, or by using automatic reception or on demand reception. • Push button operations are not possible. • All modes change to time mode. • The alarm tone and confirmation tone will not sound. (When the timer, chronograph or alarm is used) • The LED lights will not come on. • The chronograph and timer are forcibly reset and cannot be operated.

94 ◆ If the charging insufficiency occurs during radio signal reception, the operation will stop automatically, the watch will return to the time before the operation, and 2-second interval movement will begin. Regularly charge your radio controlled watch so it does not become insufficiently charged.

C. Overcharging Prevention Function When the rechargeable cell becomes fully charged by exposing the watch face to light, the overcharging prevention function is automatically activated to prevent the battery from being charged further.

No matter how much the watch is charged, it will not affect the rechargeable cell, timekeeping, functions or performance of the watch.

95 D. Guide to Charging Time Below are the approximate times required for charging when exposing the watch dial to light continuously.

96 To work for one day ... The charging time to run the watch for one day with normal movement. To become fully charged when the cell is discharged ... The time for full charging after the watch has stopped due to an insufficient charging.

[Caution] A fully charged battery will run the watch for about 6 months without further charging. The watch will maintain its accuracy for about 2 and a half years when running in the power saving mode. Charge the watch every day, as it will take a long time to recharge it, as is indicated in the table, when it stops due to an insufficient charging. We recommended that you charge the watch for a long time in direct sunlight once a month.

97 E. Handling Your Eco-Drive Watch

WARNING Handling the rechargeable cell ◆ Do not remove the rechargeable cell from the watch yourself, unless unavoidable. If you must remove the battery, store it out of reach of children to avoid accidental ingestion. If the rechargeable cell is ingested, consult a doctor immediately. ◆ Do not throw away with regular trash. Doing so could cause a fire or environmental damage. Follow the collection procedures as specified by your local authority.

Do not use anything other than the specified WARNING rechargeable cell ◆ The watch will not operate if incorrect battery types are inserted. Never use a regular battery. The battery could overcharge during the charging process and burst, causing damage to the watch or injuries to the wearer.

98 CAUTION Charging precautions ◆ Do not charge the watch in a high- environment (about 60°C / 140°F or more). Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged. Example: • Charging close to incandescent lighting, halogen lamps, or other lighting sources that easily become hot. • Charging on surfaces that can easily become hot, such as a car dashboard.

◆ When charging with incandescent lighting, halogen lamps, or other lighting sources that easily become hot, place the watch at least 50 cm (20 in.) away from the source to avoid overheating.

105 Precautions WARNING: Water-resistance performance There are several types of water-resistant , as shown in the following table. The unit "bar" is roughly equal to 1 . * WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar.

Indication Specifications Minor exposure to water Case (washing face, , etc.) Dial (case back)

WATER RESIST WATER Water-resistant to or no indication RESIST(ANT) 3 OK WATER WR 50 or WATER RESIST(ANT) 5 bar or Water-resistant to RESIST 50 WATER RESIST(ANT) 5 atmospheres OK WR 100/200 or WATER RESIST(ANT) WATER RESIST 10bar/20 bar or Water-resistant to 100/200 WATER RESIST(ANT) 10/20 atmospheres OK

106 For correct use within the design limits of the watch, confirm the level of water- resistance of your watch, as indicated on the dial and case, and consult the table.

Examples of use

Moderate exposure to Operation of the water (washing, kitchen Marine sports crown or button work, swimming, etc.) (skin diving) (with air tank) with moisture visible NO NO NO NO OK NO NO NO OK OK NO NO

107 WARNING: Water-resistance performance • Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater. • Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is water- resistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving. • Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas.

CAUTION • Be sure to use the watch with the crown pressed in (normal position). If your watch has a screw-lock type crown, be sure to tighten the crown completely. • Do NOT operate the crown or button with wet fingers or when the watch is wet. Water may enter the watch and compromise water-resistance. • If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth. • If moisture has entered the watch, or if the inside of the is fogged up and does not become clear within a day, immediately take the watch to your dealer or Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside.

108 • If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off.

CAUTION: Keep your watch clean. • Leaving dust and dirt deposited between the case and crown may result in difficulty in pulling the crown out. Rotate the crown while in its normal position, from time to time, to loosen dust and dirt and then brush it off. • Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.

Cleaning the Watch • Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal . • Use a soft, dry cloth to wipe off perspiration and dirt from the leather band. • To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer. NOTE: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish.

109 CAUTION: Operating environment • Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where are outside the specified range, may result in deterioration of functions or even stoppage of the watch. • Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn. • Do NOT leave the watch in a place where it is exposed to high temperature, such as the compartment or dash-board of a car. Doing so may result in deterioration of the watch, such as deformation of plastic parts. • Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic or a magnetic latch of a refrigerator door or clasp or the earphone of a . If this has occurred, move the watch away from the magnet and reset the time. • Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen. • Do NOT subject the watch to a strong shock such as dropping it onto a hard floor.

110 • Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored.

Periodical inspections Your watch needs inspection once in every two or three years for safety and long use. To keep your watch water-resistant, the packing needs to be replaced regularly. Other parts need to be inspected and replaced if necessary. Ask for Citizen geuine parts upon replacement.
